如何在Python中模拟abastract类或接口-使用pytest进行测试

from abc import ABC, abstractmethod

class MyAbstractClass(ABC):
    @abstractmethod
    def my_abstract_method(self):
        pass

class MyClass(MyAbstractClass):
    def my_abstract_method(self):
        print("Implementing abstract method")

my_instance = MyClass()
my_instance.my_abstract_method()

import pytest
from abc import ABC, abstractmethod

class MyAbstractClass(ABC):
    @abstractmethod
    def my_abstract_method(self):
        pass

@pytest.fixture
def my_abstract_class_instance():
    class MyClass(MyAbstractClass):
        def my_abstract_method(self):
            return "Implementing abstract method"
    return MyClass()

def test_my_abstract_method(my_abstract_class_instance):
    assert my_abstract_class_instance.my_abstract_method() == "Implementing abstract method"
